Description
Technical field
Present document relates to but be not limited to the communication technology, espespecially a kind of method and apparatus for realizing troubleshooting.
Background technology
Connectivity fault management (CFM, Connectivity Fault Management) is by U.S. electric and electronics work
Association of Engineers (IEEE, Institute of Electrical and Electronics Engineers) 802.1ag is defined
A kind of two layers of (data link layer) link, end to end, be based on virtual LAN (VLAN, Virtual Local Area
Network Operations, Administration and Maintenance (OAM, Operation Administration and Maintenance) mechanism),
Support International Telecommunication Union's telecommunication standardsization tissue (ITU-T, ITU-T fo ITU Telecommunication
Standardization Sector) defined in OAM standards, be mainly used in double layer network detect connectivity of link, really
Recognize failure and determines the position that failure occurs.To make the relevant technologies sufficiently clear, the related definition of CFM messages is carried out below
Explanation：
Safeguard domain (MD, Maintenance Domain)：MD specifies connection error detection (CFD, Connectivity
Fault Detection) network that is covered, its boundary is determined by a series of maintenance endpoints configured on device port
Justice, domain is safeguarded with maintenance domain name to identify；
Maintenance association (MA, Maintenance Association)：MA is the set for safeguarding some maintenance points in domain.Dimension
Shield association is identified with " safeguarding domain name+maintenance association name ".MA specifies serviced VLAN, transmitted by the maintenance point in MA
Message carries the VLAN tag, while the maintenance point in MA can receive the message that other maintenance points are sent in this MA, each MA
A corresponding Service Instance (Service Instance)；
Maintenance point (MP, Maintenance Point)：Configuration belongs to some MA on device port.Maintenance point can be divided into
Two kinds：MEP and Maintenance Intermediate Point (MIP, Maintenance association Intermediate Point)；
Safeguard endpoint (MEP, Maintenance association End Point)：MEP is configured on device port,
Belong to some MA, identified with an integer, referred to as MEP identifies (MEP id).MEP determines the range for safeguarding domain and boundary.
It maintenance association belonging to MEP and safeguards domain, determines the VLAN attributes and rank of the message that MEP is sent out.Safeguard that endpoint has side
Tropism is divided into extroversion and safeguards endpoint (DOWN MEP) and interior to safeguarding two kinds of endpoint (UP MEP).The direction of MEP shows maintenance
Position of the domain relative to the port；Wherein, export-oriented MEP (DOWN MEP) is to receive and dispatch CFM agreements in the port where extroversion MEP
Message, and it is interior to MEP (UP MEP) be then in equipment in the same VLAN in addition to interior other other than the port where MEP
Receive and dispatch CFM protocol massages in port；
Connectivity detection message (CCM, Connectivity Check Message) is mostly important one in CFM messages
Kind, test side periodically sends CCM messages to notice the connectivity of opposite end link；
Connectivity fault recognition message (LBM, LoopBack Message) is CFM for verifying local maintenance endpoint
(Local MEP, Local Maintenance association End Point) and reciprocity Maintenance Intermediate Point (MIP,
Maintenance Domain Intermediate Point) or opposite end MEP between two-way connectivity, be divided into unicast loopback
With multicast loopback；
Connectivity Fault Isolation message (LTM, LinkTrace Message) is CFM for confirming that communication path failure is sent out
Raw specific location；
Communication with detection time interval (CCI, Continuity Check Interval)：Safeguard endpoint send CCM in when
Between be spaced.
CFM messages are two layers of ether packet, and two-layer protocol type is 0x8902；On the exchange chip of receiving terminal, receive
Ether protocoll type is the message of 0x8902, then the message is carried out CFM Message processing flows.Since CFM supports ITU-T definition
OAM standards, so protocol Data Unit (PDU, the Protocol Data Unit) content of CFM messages using ITU-T define
OAM data format.CFM messages are divided into as export-oriented Connectivity Fault Management (DOWN CFM, Down Connectivity
Fault Management) message and interior to Connectivity Fault Management (UP CFM, Up Connectivity Fault
Management) message, UP CFM messages are initiated and are terminated in UP MEP, and DOWN CFM messages are generated from master control borad and initiated,
Peer node master control borad is sent to through Network-Node Interface (NNI, network to network interface) to terminate.
In the related art, when exchange chip supports hardware UP MEP in the network equipment, exchange chip sends UP MEP
Message need not specify forwarding port, UP MEP messages in addition to MEP associated ports other with vlan port carry out routing turn
Hair.And if when exchange chip does not support hardware UP MEP, central processing unit (CPU) software function can only be used to realize UP MEP
Message is sent, and this mode can consume a large amount of cpu resources in periodicity sending CFM (for example, CCM) message, while also can
Increase the complexity of system software processing, becomes problem to be solved in CFM process fault detections as a result,.

Based on above setting, fault handling method of the embodiment of the present invention includes：
First, after receiving CFM messages with the first forwarding port of the first MEP bindings in the first equipment, judge the first MEP
The working condition of first forwarding port of binding abandons if the first forwarding port of the first MEP bindings is block states
The CFM messages received；If the first forwarding port of the first MEP bindings is forward states, the CFM received is parsed
Message, the hardware forwarding table item obtained according to parsing forward the CFM messages to the second equipment (the 2nd MEP)；
Optionally, in the embodiment of the present invention, CFM messages may include：Detection of connectivity message (CCM, Connectivity
Check Message), two layers of ether packet that other two-layer protocol types in addition to CCM are 0x8902 (such as：Link trace
Message (LTM, Link trace Message), loopback message (LBM, Loopback Message)) etc. type of messages；Wherein,
CCM is that the exchange chip in the first equipment is pre-set according to MA and the first MEP according to scheduled sending cycle
Configuration information and protocol requirement encapsulate, and are then forwarded to the first forwarding port, and specific encapsulation process can be this field
The usual encapsulation of technical staff, details are not described herein again；
Two layers of ether packet that other two-layer protocol types in addition to CCM are 0x8902 (such as：LBM, LTM etc.) by first
CPU in equipment is when determining that current configuration information is correct, according to being sent to the first forwarding port after protocol encapsulation；It is currently configured
Information includes：MD titles, MA titles, associated services VLAN, LMEP, first forwarding port physical state and logic state；
Then, after receiving CFM messages with the second forwarding port of the 2nd MEP bindings in the second equipment, judge to receive
CFM messages type；If the CFM messages received are CCM messages, branch one is executed；If the CFM messages received are
Other unicast two-layer protocol types of non-CCM are two layers of Ethernet message (for example, LBM messages) of 0x8902, execute branch two；Such as
Two layers of ether packet that other multicast two-layer protocol types that the CFM messages that fruit receives are non-CCM are 0x8902 are (for example, LTM is reported
Text), it is forwarded directly to CPU, then executes branch three；
In this step, each type of message can pass through preset field in CFM messages (such as field selection coding
